-blocking, asynchronous reading out of the box. Apparently
it does not.
So, my question is hereby revised as such: how can I implement a
non-blocking read of a subprocess pipe that can write data to the
Tkinter text widget in an manner that does not cause the GUI to lock up?

The results look right! I did a rather large test and the checksum passed.
I will hold off any speed ups as you suggested.

This is a good solution thanks. You should wiki this somewhere.
For extra points is there a way to speed up the p.stdout.read(bufsize) ?

Thanks everyone for your replies.
Chris,
Unfortunately, I can't redirect the output to a file because there are other
processes which use this processes output as stdin.
Rob,
I will give this a try.

I have a process like this,
def run(cmd):
#cmd=a process which writes a lot of data. Binary/ASCII data
p=subprocess.Popen(cmd,stdout=subprocess.PIPE)
I would like to get cmd's return code so I am doing this,
def run(cmd):
p=subprocess.Popen(cmd,stdout=subprocess.PIPE)
rc=p.poll()

For security reasons, some programs use direct access to the TTY system
for password entry rather then reading from stdin. Most of these programs
provide anoth

Hi all,
I'm having a problem with subprocess.Popen. It seems that its unable to
capture the pg_dump's standard inputs & outputs in a non-shell mode:
from subprocess import Popen, PIPE
# fire pg_dump in order to read data from the file object pgsql.stdout
pgsql = Popen(['/usr/bin/pg_dump',
